Description

Automatic lifting chair

Technical field

The present invention relates to one way of life apparatus field, be specifically related to a kind of automatic lifting chair.

Background technology

The height of general seat is all fixing, and also some seat can be elevated, and as foot-operated, vapour-pressure type, foot-operated operation is not too convenient, and vapour-pressure type is highly unstable.If energy automatic lifting, it is best for accurately locating again.

Summary of the invention

Technical problem to be solved by this invention, for the present situation of prior art, provides a kind of automatic lifting chair.

The present invention's adopted technical scheme that solves the problem is: automatic lifting chair, as shown in Figure 1, comprises chair back and seat board 1, chair supporting seat 8 two part.It is characterized in that chair back and seat board 1 have light measuring sensor 2, controller 10 above; Chair back and seat board 1 have motor and braking 3, battery 9, cross U-shaped bracing frame 4 below, and cross U-shaped bracing frame 4 has thrust bearing 5 below, and motor shaft connects with screw rod 6 cross gap; Chair back and seat board 1 have four leads in corner below, and lead and chair supporting seat 8 are slidably matched, and there is slip locating piece 7 lead lower end, and slip locating piece and chair supporting seat 8 four sleeve internal chutes are slidably matched; There is threaded sleeve pipe in the middle of chair supporting seat 8, coordinate with screw rod 6; Chair supporting seat 8 four jiaos has four sleeves, respectively with chair back and seat board 1 below four, corner lead be slidably matched, have the chute that upper end is obstructed in sleeve; As shown in Figure 3, controller 10 has highly lock 11 buttons, automatic 16 buttons, heighten 12 buttons, turn down 15 buttons, power supply drives 13 buttons, power supply closes 14 buttons.

Compared with prior art, because the present invention adopts motor to drive, screw rod is elevated, and photo measure, regulates automatically, manual fine-tuning, and accurate positioning is easy to operate, can meet the instructions for use of user.

detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.

Automatic lifting chair, as shown in Figure 1, comprises chair back and seat board 1, chair supporting seat 8 two part.It is characterized in that chair back and seat board 1 have light measuring sensor 2, controller 10 above; Chair back and seat board 1 have motor and braking 3, battery 9, cross U-shaped bracing frame 4 below, and cross U-shaped bracing frame 4 has thrust bearing 5 below, and motor shaft connects with screw rod 6 cross gap; Chair back and seat board 1 have four leads in corner below, and lead and chair supporting seat 8 are slidably matched, and there is slip locating piece 7 lead lower end, are slidably matched with chair supporting seat 8 four sleeve internal chutes; There is threaded sleeve pipe in the middle of chair supporting seat 8, coordinate with screw rod 6; Chair supporting seat 8 four jiaos has four sleeves, respectively with chair back and seat board 1 below four, corner lead be slidably matched, have the chute that upper end is obstructed in sleeve, stop chair back and seat board 1 lead to skid off; As shown in Figure 3, controller 10 has highly lock 11 buttons, automatic 16 buttons, heighten 12 buttons, turn down 15 buttons, power supply drives 13 buttons, power supply closes 14 buttons.

Measure people's elevation principle: as shown in Figure 4, optical sensor, by utilizing emitted light, runs into people 17, reflects, measure the horizontal range of people to optical sensor, horizontal line and people's peak line angle.Signal is sent to microprocessor, and microprocessor calculates horizontal line to people's peak height, adds that horizontal line arrives ground level, draws the height of people.When measuring the horizontal range of people to optical sensor and be less than the length of chair seat board, then stop measuring.Optical sensor sectoring can measure left and right, people above in scope.

Electrical equipment control principle: as shown in Figure 2, drives 13 buttons by power supply, and acquiescence automatically, when people walks close to chair, optical sensor measures people to the horizontal range of optical sensor and horizontal line and people's peak line angle, and signal is sent to microprocessor, microprocessor calculates the height of people, divides dimension scale by partes corporis humani, calculates seat height, instruction is sent to motor, electric machine rotation, seat support raises and puts in place, after people takes, can press and heighten 12 buttons or turn down 15 buttons, be transferred to optimum height.When people leaves seat, microprocessor time delay a period of time, automatically restore to elemental height.People is away from keyboard or be oneself use always, can by highly locking 11 buttons, and seat height keeps always.By automatic 16 buttons, restPose, as shown in Figure 5.

Implementation process: opening power, people walks close to chair, and seat support raises and puts in place, after people takes, can press and heightens 12 buttons or turn down 15 buttons, be transferred to optimum height.When people leaves seat, chair time delay a period of time, automatically restore to elemental height.People is away from keyboard or be oneself use always, can by highly locking 11 buttons, and seat height keeps always.By automatic 16 buttons, restPose, as shown in Figure 5.
